Bolt.new Preview Not Updating
Quick Answer
WebContainer state can get stale. The preview panel doesn't always hot-reload correctly. Start with "Refresh the preview" before making broader code changes.
You're in the right place if...
- !Preview shows old version
- !Changes in code don't reflect in preview
- !Preview is stuck or frozen
Why this happens
WebContainer state can get stale. The preview panel doesn't always hot-reload correctly.
Fix
Refresh the preview
Click the refresh icon in the preview panel (circular arrow).
If still stuck
Close and reopen the preview panel. If that doesn't work, hard refresh the entire Bolt.new tab (Ctrl/Cmd + Shift + R).
Last resort
Start a new project and paste your current code. This resets the WebContainer entirely.
Prevent this next time
Save/export to GitHub regularly so you can always start fresh without losing work.
Frequently Asked Questions
WebContainers run in your browser. Memory pressure or long-running processes can cause the preview to stall.
No. Refreshing the preview doesn't affect your code. Only starting a new project loses unsaved work.
